As suggested by Adrian in #12699 (comment), to fix the import error, we can try importing it within the method instead of importing it at the top of the file.

ImportError: cannot import name 'CPUAccelerator' from 'pytorch_lightning.accelerators.cpu' (/home/runner/work/pytorch-lightning/pytorch-lightning/pytorch_lightning/accelerators/cpu.py)
